I'm making an amv, and i'm trying to use the song Getting away With Murder by Papa Roach. The song is normally 3:10 seconds long, but when I import it over to WMM it changes to 5:16 and strange things happen.

When I play the song, it's fine. The music ends at 3:10 like it's supposed to but there's a long strip of audio left, even though the music has ended. Also, while I'm playing the song, and when I reposition the line (or whatever it's called) the song changes it's position. For example, let's say im on 1:12, and I let it play a little. And when I put the line on 1:12, the audio plays what it's supposed to play when it's at 2:00 or something.

Sorry if i'm not clear, I have no other way of explaining it. Here's a screen shot
